Letters Patent No. 94,026, dated August 24, 1869.

IMPROVEMENT IN PORTABDE HEATING-ATTACHMENT FOR S'IO'VEFS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, J OHN S. PERRY, of Albany, in thecountyof Albany, and State of New York, have invented a new and improved Portable Heating-Attachment for Stoves and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which-.-

Figure 1, sheet 1, is a perspective view, showing one form of my improved heater applied to a cooking-stove.

Figure 2, sheet 1, is a longitudinal section, taken vertically through the centre of the heater.

Figure 3, sheet 1, is a section, taken transversely through theccntre of the heater.

Figure 4, sheet 2, is a sectional view of an improved heater, diiiering somewhat from that shown in figs. 1, 2, and 3.

Similar letters of reference indicate corresponding parts in the several figures.

The nature of my invention consists First, in a portable warming-chest, containing a fixed or removable water-reservoir, and adapted for being applied to or detached from the escape-pipe of a stove, for cooking or heating-purposes, so asto receive' the heated products of combustion on their way from such stove to the main flue or chimney, and thereby utilize a large percentage of the heat for warming'watcr or other purposes, as will be hereinafter explained.

Secondly, in aport-able heating-chest, containing a water-reservoir, in combination with a pendulous escape-pipe, or a pipe which is carried'below the top of said chest, either through the said reservoir, or on one 1 thereof, whereby the heated products received from the fines of a stove will be caused to accumulate about the walls of the reservoir, and communicate a large. amount of heat to the water therein, as will be hereinafter explained.

.Thirdly, in a portable chest, which is provided with inlet and outlet-pipes, a water-reservoir, and a warmingcloset,so arraugeth'that when applied to a stove, the heated products leaving the tines of the stove shall circulate around the walls of the reservoir and closet before escaping from the chest, as will be hereinafter explained.

I am aware that-portable radiators and drums of various descriptions have been used in conjunction with the escape-fines or pipes of stoves, for receiving the products of combustion on their way to a chimney, and thus radiating a large amount of heat into apartmerits. I am furthermore-aware that it is not new to construct cooking-stoves with permanent extended fluechambers, constituting parts of the bodies of the stoves, for receiving or containing water-reservoirs, and allowing the heated products of combustion to circulate about the walls of the reservoirs before escaping into v I am not aware that a portable apparatus or-heater, adapted for being applied to any size or form of stove,-

communicating with the dues thereof, and constructed snbstantially'as hereinafter described, has ever been known or used prior to my invention thereof.

To enable others skilled iu-the artto understand my invention, l will describe the best means known to me for carryingit into effect.

In the accompanying drawings- A represents a chest, which may be made of any suitable capacity or shape, and which maybe composed, wholly or in part, of sheet or castmetal,- properly mounted and strengthened.

B is the base of this chest, which may be so applied as to be removable, for cleaning the interior of the chest, and removing, from time to time, accumulations of soot and ashes which will collect therein.

G is a pipe or orifice through one side of the chest, which is adapted to receive the collar around the es cape-flue of a stove, or to receive a pipe leading from such escape-flue, in order to establish communication between a stove and the interior of a chest.

D isa water-reservoir, which is sustained, by its top flange, upon the top plate of the chest A, so that its bottom and side walls will be exposed to the action of the heated products of combustion caused to circulate within the chest, and so that a chamber, P, will be formed around the reservoir, for containing and retain ing a large amount of heat.

This water-reservoir D, which may be permanentlyfixed to chest A, or detachable therefrom, has openings through its top, provided with hinged covers I) b and it is also constructed with a flue, 0 passing up centrally through its interior, and out through a top plate between the doors or covers I; l), as shown'in figs. 1, 2, and 3. i

This flue or pipe is adapted for receiving, in its lower v,

end, a pipe, 0 which, if used, extends down nearly to the bottom of chest A, on one side of the centre thereof, and servesto conduct the spent products of combustion, through pipe 0 to the main flue or chimney,

afterthe products circulate through the interior of the chest.

The pipe 0 communicates with the ascending flue 0 near its upper end, and lies in a horizontal position, directly inv line with the inlet-orifice O, as shown in fig. 3.

This pipe or flue'C 'is provided with a damper, g, Y

which can be regulated by a rod, g, extending outside of the case, A, as shown in fig. 2.

Below pipe -O and extending'horizontally through' surrounding the water-reservoir.

the chest A, is a closet or chamber, G, closed, at one or both ends, by doors a, and surrounded by a chamber, c.

When the chest A is put in communication with the escape-flue of a stove, and fire made in the latter, the

escaping products will enter this chest through the orifice G, andrise therein, and fill the dead-air space P,

As the chest beco'm'es warmed, the products will descend, around the warming-closet G, to the base B, thence rise through pipes Cl 0 and escape into the chimney. If a direct draught is required at anytime, the damper g is opened, which will cause most of ,the pro-: ducts to pass directly from orifice 0, through pipe 0, into the ascending pipes 0 0*.

.The pipes G 0 may be dispensed with, and the products carried-off through the pipe 0 as shown in fig. 4, sheet 2; and, if desirable, this pipe 0 may be arranged outside of the water-reservoir, although, when carried through it, a large amount of heat will be communicated .to the'water in this reservoir, which would in this space, they will descend, and give place to a further supply of heat.

While I prefer "to utilize the space beneath the water-reservoir D, for containing a wanningrcloset, I do not confine myself to the use of such closet; and while I prefer to arrange the water-reservoir wholly within the chest A, so that its side'and bottom walls shall not be impinged upon by cold air, I do not confine myself to such arrangement, as a part of the reservoir may be exposed above the top of the chest.

My improved portable warming-chest and reservoir combined is adapted for being fitted closely to the hack ,of a flat-back stove, as shown in fig. 4, sheet 2, so that a large amount of heat will be radiated into the chest through this back wall. If constructed for such-a. stove,

I am not restricted to .size or shape in the construction of my portable heaters, for they do not constitute a part of the body of the stove to which they may be applied; and they may be applied to stoves, ranges, furnaces, or heating-apparatus of various descriptions, which materially differ from them in size and shape.

I do not claim as my invention such a heating-attachment as is shown in the schedule annexed to the Letters Patent of George \V. Gillet, dated December 29, 1868.-

Having described my invention, i

What I claim as new, and desire to secure by Letters Patent, is-

1. Aportable warming-attachment'for stoves, con sisting of a chest, A,Aa reservoir,]), and inlet and out let-passages, adapted to operate substantially as dd" described. y 2. A portable warming-attachment.for stoves, (3')!!!- bining the following elements, to wit, a chest, A, an outlet-flue, G, a warming-ch set, G, and an inlet-ori- -fice, O, substantially as described.

3. The direct flue 0, provided with a damper, g, and arranged, in the relation described, to the inlet-orifice U, for the purpose described.

4. The descending flue 0 0 passing through the reservoir 1 and extending down nearly to the bottom of the portable chest A, within which such reservoir is arranged, substantially as and for the purpose described, J OHN S. PERRY.
